RAILWAY CROSSING.

Application filed May 29,

To all whom it may concern:

Be it known that 1, ANTHONY E. GARL- SON, a citizen of the United States, at Los Angeles, in the county of L les and State of California, have certain new and Railway Crossings, is a specification.

My invention relates to improve residing 0s Angeinvented useful Improvements in of which the following ments in railway crossings in which the rails cross one another at any angle or curve, in conjunction with swinging frog members; and the objects of my improvements are, first,

to provide a continuous runningcar wheels to roll the flange of the said car wheel to p surface for over, with clearances for ass thru;

second, to ai'ford facilities for the ad ustment or renewal of any worn or broken parts independently of the connecti rails leading to the and, third, to reduce the poundin wheels to a minimum as rail to the other on car wheels.

ng tr acksaid railway crossing;

g of the they roll from one the said crossing at any speed, and to prevent broken rails or flat A further object of my invention is to provide a noiseless crossing which may be manually, mechanically or automatically operated. I

V I attain these objects by the illustrated in the accompanying in which:

Referring to the drawingsin which like characters of reference designate similar parts, secured thereon, the faces 2 1- and the inner sides of the rails 3 tively, and may be set to any angle in a railway crossing. where the,

1 represents a plate with rails 3 and fl:

23 form and 4r. respecor curve same is to be used, the said rails 3 being joined together at their points 25, the two rails 4 being in turn extended in a line adjoining with the said rails 3, the faces 17 being curved on the inner ends. of the said rails, and the said faces 17 swinging nwardly on a line joining the outer portion of the rails te rs,

4t to the said faces 23 thereon, with the pins 7 as the center of the said curved faces, and the said faces 17 .forming tangents between the said faces 23 and 24:, the frogs 2 'and 2 areoper'atively secured on the pins 7 between' the said faces 24: and 17 the pins 7 being secured to the plate 1, and the faces 17* are curved around the said pins 7 as cen-- to correspond operatively with the said faces 17K The straight faces 10 form the sides of the frogs 2 and 2 at points extending from the pins 7 to the faces 17 The arms 12 and 13 are integral with the said frogs 2 and 2 respectively and extend therefrom a distance to points opposite the faces 23 on the rails 4. The faces 11 are formed on the arms 12 and 13 so as to be positionedat an angle to the faces 23 when the arms 12- or 13 are held in a closed position, as shown in Figure 1, and when the said faces 10 and 2 are positioned parallel to one another the said arms 12 and 13 are held in, an open position, as shown in profilein Figure 1. Again, the faces 11 are formed on the arms 12 and 13 so as to be positioned at an angle to the faces 23 when the said frogs 2 and' 2", and arms 12 and 13, are held in a closed position. llhe arm12 is extended operatively under the arm 13 on the plate 1, and the arm 13 is in turn extended operatively' over the arm 12, with the groove 16 positioned flush with the face 17-, between the frog 2 and the. arm- 13. The sockets 15 and the keys 1d are integral with the inner portions of the said arms 12 and 13 and mesh together when the said'. frogs 2 and 2 are in their open positions, as shown in profile in Figure 1. The springs 5 are operatively positioned in theplate 1 underthe frogs2 and 2 and are held in theircompressed positions by the lu s 6, thelugs 6 being integral with the said re s 2,and 2 and extending into the recesses 2 the said recesses 27 being positioned in the plate 1. p u 1 Y The guides-'18 are secured on the plate 1 at an angle to thesaid faces 24, on a line corresponding to the faces 10 when the frogs and 2 are in .a closed position, and the guides19 are also secured on the plate 1 at an angle to the said faces 23, on a line corresponding to the faces 11 when the arms 12 and 13 are in a closed position;

The plate 26 is secured to the'corner porbetween, the said guides.

19, with a tongue 29 positioned on the innercentral portion thereof, and is formed to clear the said arms 12 and 13 when thrown into open position. The fingers 8 are integral with the said arms 12 and 13, and extend therefrom a distance to swing operatively into the opening 9, the said opening-9 is formed in the bottom face 9f the plate 26 and the tongue 29. The grooves 20 are formed in the points 25 of the rails 3, a distance below the top surface thereof, and the notches 21 are formed in the frogs 2 and 2 between the said faces 17 and 10 so as to fit slidably into the said grooves 20. A hole 22 passes thru the plate 1 at a point between the faces 24 and 23 of the rails 3 and 4: respectively, and is disposed under the said frogs 2 and 2 and the arms 12 and 13. The guides 28 and 30 are positioned beneath the frogs 2 and 2 and are secured to the plate 1, and the rails 3 and 4 respectively. The bevels 31 and 32 are formed on the faces 11 and 10 respectively, and slope down a distance from the top faces of the said frogs 2 2 and the arms 12, 13 respectively, to the said faces 11 and 12.

In the operation of my railway crossing the frogs 2 2 and the arms 13 and 12 are held in their closed positions by the springs 5, thus holding the faces 10 and 11 to the faces 24; and 23 respectively at an angle to one another, and as a car wheel rolls over the rails '3 from either direction towards their points 25, and the rails 4, the flange on the said car wheel wedges between the faces 24 and 10, and'spreads either one of the frogs 2 or 2 into an open position, depending upon the direction from which the said wheel is rolling. Thus by spreading the said faces 10 on the frogs 2 and 2 from the faces 24 on the rails 3, an unbroken rolling surface is provided over the rail 3, the frog 2 and the rail 4, in one direction, and the rail 3, the frog 2 and the rail 4 in the crossing direction. When the said car wheel is rolling from the opposite directions to those hereinbefore described, beginning from the rails 4, thence over the frogs 2 or 2*, to the rails 3, the flange of the car wheel first rolls between the faces 23 and 11, and spreads either of the arms 13 or 12 into open positions, and thus an unbroken rolling surface is provided over the rail. 1, the frog 2 and the rail 3, in one direction, and over the rail 4., the frogv 2 andthe rail 3 in the crossing direction. The. groove 16 provides passage for the flangeof the car wheel to pass thru when rolling over the frog2 a car wheel will only roll from one of the crossing directions over the frogs 2-, or 2*, it will be noted that when the arm 13 is thrown open as hereinbefore' described and shown in profile in Figure l, the arm 12 is locked in a closed position by the key 14. by meshing into the socket 15, and when the arm 12 is in turn thrown open the arm 13 is likewise locked in a closed position by the key 14 by meshing into the socket 15.

- The fingers 8 slide within the opening 9 and prevent the arms 12 and 13 from jumping above their upper level, and the guides 28 and 30 in turn form a seat under the frogs 2 and 2 to prevent them from dropping beneath their lower level, and when the opening 9, guides 28 and 30 are arranged as hereinbefore described, top and bottom bearings are formed for the said arms 12-13 and the frogs 2 b respectively.

The guides 18 and 19 will receive the flange of the car wheel when rolling into the said crossing from a point before reaching the faces 11 and bevels 31, and faces 10 and bevels 32 respectively, and will slide theflange of the said car wheel on the rails 3 and 4 sideways, to bring the said flange of the car wheel in a line with the faces 11 and bevels 31, or the faces 10 and bevels 32 respectively, depending upon the direction from which car is moving.

The bevels 31 and 32 are arranged to con form with the beveled face on the flange of the said car wheel, to prevent climbing thereof over the frogs 2"-2 or arms 12--13 when opening the crossing, as hereinbefore described.

The hole 22 is arranged under the said crossing to allow any obstruction between the joining portions of the rails 34, frogs 22 or arms 1213 respectively, to pass therethru to a cleanout means.

Having thus described my invention, what I claim is:

1. In a railway crossing of the class described, a plate support, two joined rails pointed together, and two adjoining rails disposed in alinernent with the said joined rails, adapted to be mounted on the said late, pair of frogs operatively positioned etween the said joined rails and the adjoining rails respectively, arms extending from the said frogs. a guide means provided at the adjoining ends of the said joined rails and pair of frogs, adapted to operatively hold the top faces ofthe said frogs and the. arms flush with the top faces of the said rails. as set forth.

2. Tu a, railway crossing of the class described. a plate support, two joined rails pointed together, and two adjoining rails disposed in alinenient with the said joined rails, adapted to be mounted on the said plate, a pair of frogs operatively positioned between the said joined rails and the adjoining-i rails respectively. arms extending from the said frogs, a guide means, adapted to operatively hold the top faces of the said frogs and the said arms flush with the top surface of the said rails, a scavenging means, adapted to release obstructions thru the said plate support, an automatic operating means in connection with the said 3. In a railway crossing of the class described, a plate support two joined rails pointed together, and two adjoining rails disposed in alinement with the said joined rails adapted to be mounted on the said plate, a pair of frogs operatively positioned between the said joined rails and the adjoining rails respectively, arms extending from the said frogs, fingers extending from the said arms, adapted to sllde Within a hearing means a beveled-faced guide means, adapted to direct the ear wheel into the said crossing, a locking means, adapted to hold the said crossing into its relative open and closed position, a scavenging means, adapted to release obstructions thru the said plate support, an automatic operating means in connection with forth.

In testimony whereof I affix my signature.
